Chapter 4: Problem 10

Logical operators have __________ precedence than relational operators.

Short Answer

Expert verified
Answer: Logical operators have lower precedence than relational operators.

Step by step solution

01

Understand the concept of operator precedence

Operator precedence determines the order in which operators are evaluated in an expression. Operators with higher precedence will be evaluated before operators with lower precedence. For example, in the expression 2 + 3 * 4, the multiplication operator (*) has higher precedence than the addition operator (+), so the result will be 2 + (3 * 4) = 14, not (2 + 3) * 4 = 20.
02

List relational operators

Relational operators are used to compare two values and return a boolean result (true or false). The relational operators are as follows: 1. Less than (<) 2. Greater than (>) 3. Equal to (==) 4. Not equal to (!=) 5. Less than or equal to (<=) 6. Greater than or equal to (>=)
03

List logical operators

Logical operators are used to combine multiple boolean expressions and return a single boolean result (true or false). The logical operators are as follows: 1. AND (&&) 2. OR (||) 3. NOT (!)
04

Comparing precedence of logical and relational operators

In most programming languages, relational operators have higher precedence than logical operators. This means that in an expression containing both relational and logical operators, the relational operators will be evaluated first, followed by the logical operators. For example, in the expression `3 < 4 && 5 > 2`, the relational operators `<` and `>` have higher precedence than the logical operator `&&`. First, the expression `3 < 4` will be evaluated (which is true), then the expression `5 > 2` will be evaluated (also true), and finally, the logical operator `&&` will combine the two boolean values (true && true), resulting in a final value of true.
05

State the answer

Based on the comparison of precedence between logical and relational operators, we can conclude that logical operators have lower precedence than relational operators.
